stdlib_ssyrk Subroutine
public pure subroutine stdlib_ssyrk(uplo, trans, n, k, alpha, a, lda, beta, c, ldc)
SSYRK performs one of the symmetric rank k operations C := alphaAAT + betaC, or C := alphaATA + betaC, where alpha and beta are scalars, C is an n by n symmetric matrix and A is an n by k matrix in the first case and a k by n matrix in the second case.
